❓ FREQUENTLY ASKED QUESTIONS (FAQ):

Q: How do I get the lowest audio delay (latency)?
A: For absolute zero-lag live audio, connect your phone to the speaker using a standard 3.5mm AUX cable. Bluetooth inherently introduces a small wireless transmission delay depending on the speaker's hardware.

Q: How do I stop annoying echo or screeching feedback?
A: Audio feedback happens when the speaker output enters the phone's microphone. Keep your phone slightly behind or at a distance from the speaker, or adjust the volume level.

Q: Can I use this with Bluetooth headphones or wireless earbuds?
A: Yes! You can stream your microphone audio directly into wireless headphones, earbuds, or Bluetooth car stereos.
